Heat 1 tablespoon olive oil in a saucepan set over medium-high heat until shimmering. Add dry couscous and a hearty pinch of salt and pepper and cook, stirring occasionally, until lightly toasted, about 3 to 4 minutes.

Meanwhile, heat 2 1/4 cups of water in the microwave until very hot or barely boiling (about 90 seconds at high power should do it). When couscous is toasted, stir in hot water (careful, as it will steam and sputter). Cover, reduce heat to medium-low, and simmer for 8 to 10 minutes or until water is absorbed and couscous is al dente. Transfer to a bowl and let cool.

When couscous is cool, toss with remaining 3 tablespoons olive oil, zucchini ribbons, sliced basil, and pine nuts. Season generously to taste with salt and pepper. Divide among serving bowls and top with shaved Pecorino and micro basil (if desired).
